....to the user summary information instead of a simple listing of query results. Di#erently from our approach, the authors never consider timing relations between objects, while they manage to hide querying of heterogeneous data on distributed repositories with an unified user interface. Delaunay [4] is a framework for querying and presenting multimedia data stored in distributed data repositories. The user specifies a multimedia presentation spatial layout by arranging graphical icons. Then, each icon is assigned module clip story scene section section scene clip Fig. 1. Hierarchical ....

....is constraint based and supported by a constraint solver. Our approach uses a context sensitive graph grammar formalism which we believe is more intuitive. Inspired by the work of Weitzman and Wittenburg, Cruz and Lucas developed a visual querying and presentation system called Delaunay [5]. As a multimedia extension to Delaunay that was designed to visualize object oriented databases, Delaunay allows the user to specify the layout of a multimedia document in a set of style sheets and provides a query language interface for the user to query object oriented database and the Web. ....

....interface issues have attracted signi cant attention in many areas of computer science and information systems. Investigations and developments have centered mostly around developing user interface tools in the form of browsers and query interfaces for the purpose of visual access to databases [7]. In these platforms, visual forms are generated for guiding users in the exploration of database contents, mainly using the associated database query sub language in the background. In a di erent approach, a new visual query language is developed to form queries independent of the database sub ....

....the internal query language. The QBD visual query language is based on an entityrelationship at the external level and uses SQL internally. A query is expressed by selecting an entity, then following a path by choosing a relationship. Conditions can be expressed on attribute values. Delaunay MM [6] is a framework for querying multimedia data stored in distributed data repositories including the Web. The Delaunay MM query interface provides a format in which the user can enter SQLlike object queries. The queries are then translated into the syntax accepted by the destinations. SEMCOG ....

Architecture of Delaunay MM Figure 1 provides an overview of the Delaunay MM architecture for querying and presenting multimedia data retrieved from digital libraries (Cruz James, 1999b) This new architecture builds on the visual querying and layout design methods previously developed (Cruz Lucas, 1997) (Cruz Lucas, 1999) Users begin by submitting keywords for their query. They may also select a layout style for result display, information repositories for querying, and the type of media objects to return (image, text, audio, or video) at this point (see Figure 2) These parameters are ....

....are predefined by a layout designer. The designer, drawing upon his her knowledge of human computer interaction and layout principles, creates and saves layout templates for a specific user group. These templates are created using the visual specification tools available through Delaunay MM (Cruz Lucas, 1997) (Cruz Lucas, 1999) When query results are returned, these templates are populated with the results. Notably, these templates are static. Thus, the final layout is not dependent upon the actual query results; rather it depends solely on which template is selected. In the current version of ....
